GEORGE KREMENTZ, OF

NEYVARK, NEW JERSEY.

MACHINE FCR MAKING COLLAR=BUTTONS.

SPECIFICATION forming part of Letters Patent No. 372,683, dated November8, 1887.

(No model.)

To (LZZ whom, it may concern:

Be it known that I, GEORGE KREMENTZ, of Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Machines for Making Collar-Buttons, of which thefollowing is a specification.

This invention relates to a new and improved machine for making thecollar-buttons for which Letters Patent of the United States weregranted to me under date of the 6th day of May, 1884, No. 298,303, andother similar collar-buttons or parts thereof.

The invention consists in the combination, with a series of dies fordrawing in the buttonblanks, of rotating rods for rotating the buttonsor blanks during the time that they are being drawn and mechanism forshifting the button at regular intervals.

The invention also consists in the construction and combination ofnumerous parts and details, all as will be fully described and set forthhereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of myimproved machine for making collar-buttons and like articles. Fig. 2 isa rear view of the same. Fig. 3 is a side view of the same. Fig. 4 is asectional plan View, on an enlarged scale, showing the devices forrotating the blanks, the bars for shifting them, and the mechanism foroperating the blank-rotaters and other parts. Fig. 5 is an enlargeddetail front view of the blankrotaters, blankshifters, and parts foroperating the same, parts being broken out. Fig. 6 is an enlargedlongitudinal section of the middle part of the machine, showing theblankshifters in section, the die-plates in section, and an end view ofthe frame containing the blank-rotators, also showing the parts foroperating the blank-rotators.

Fig. 18 is a cross-sectionalview. of the button as it leaves the machine.

Similar letters of reference indicate corresponding parts.

In the upper part of the frame A of the machine the shaft A isjournalcd, and on the same the disks B and B are mounted eccentricallyon the front and back of the machine, respectively, which disks aresurrounded by straps or bands connected with rods. At the front of themachine the rod B is connected with the eccentric, and to the lower endof said rod 13 the reciprocating cross-piece or hammer O is pivoted,which is guided between the guides G on the front of the machine. To thesaid cross-piece or hammer C the upper die is fastened, which will bedescribed hereinafter.

On the rear end of the machine the rod B is connected with the straparound the eccentric B, and the lower end of said rod 13 is connectedwith a frame, D, mounted to reciprocate vertically between the guides D,the said frame D being provided with a recess or open ing, D into whichone end of the shaft E projects, said shaft being journaled in bearingsof the frame of the machine, as shown in Fig. 3. In the recess D" aratchet-wheel, E, is mounted on the shaft E, with which a pawl, E",engages, acted upon by a spring and pivoted to thevcrtically-reciprocating frame D. A suitable check pawl, E, engages withthe ratchetwheel and is pivoted to the frame of the machine. In the topof the reciprocating frame D a pawl, E", is pivoted, which acts on andrevolves a ratchet-wheel, E, united with a cogwheel, E, engaged with thecog-wheel E mounted on a squared shaftinserted in one end of atubularshaft, F, Fig. 4. A suitable locking-pawl is engaged with theratchet-wheel E. On the shaft E a disk, F, is mounted, which is providedon one face with a projection, F,

s2 erases shaft, G, is passed, said shaft beingjournaled' in a box orframe, G. On the shaft G the cog-wheel G is'mounted, and is engaged witha pinion, G mounted rigidly on a sleeve, G in which a rod, G is mountedto reciprocate or slide. A series of rods, G and surrounding sleeves ortubes G are mounted parallel and transversely in the frame G, thepinions G of the several sleeves G being engaged, as shown in Fig. 8.The ends of the rods G projecting from the front of the easing, are eachprovided with a head or cap,G, having a recess closed by a rubber heador disk, G. The several sleeves G also pass through a bar, H, restingagainst the inner surface of the front of the box Gand mounted at itsends on transverse rods H of the box- G, so as to adapt said bar H toslide transversely to the lengthof the box. Said bar H also restsagainst cam-arms H fixed on shafts H in recesses in the rear surface ofthe front of the box G, said shafts H being provided with arms H,resting between pins H on a bar, H", guided in the ends of the box G toslide in the direction of the length of said box. The bar H also has adownwardly-extending pin, H passed through a slot in the free end of anarm, I, on the upper end of a shaft, 2, mounted to turn' on itslongitudinal axis, and provided on its lower end, below the platform A,with an arm, 1 on which a projection, 1 of a disk, I", on the shaft Ecan act, as shown in Fig. 3.

As shown in Fig. 9, the cam projections 11 rest in the recess in therear surface ofthe box G, so as to permit the bar H to rest snuglyagainst the rear side of the front of the box G. Each sleeve G issurrounded, directly behind the bar H, by a collar, J, through which ascrew, J, passes, said screw also passing through the corresponding rod,G and through the longitudinal slots J of the sleeve G which sleeve G issurrounded b a s )iral s rin J b7 one end of which rests against thepinion G of the sleeve and the other end against the correspondingcollar, J. When the bar H is moved in the direction of the arrow 00,Fig. 9, the bar H is pressed from the inner surface of the front of thebox G by the cam-arms H whereby the collars J are moved in a likedirection, as are also the shafts G connected with the collars J, andthe springs J are compressed.

In front of the box Gtwo bars, K and L, are provided, of which the lowerbar, K, is provided along the front with a rib, K, on the top, said ribbeing provided with as many segmental notches K as there are rods G inthe box G, the centers of the said notches being directly below thelongitudinal axes of the rods G The upper bar, L, is provided on itsfront, at the bottom, with a rib or ridge, L, provided with alongitudinal groove, L said groove L being directly above the notchesK".

A Ushaped plate, M, is fixed on top of a frame, R, to be describedlater, and is provided with two laterally-projecting wings, M From theends of the bar L pins L project.

downward. and rest on the ends of the wings M said pins also passingthrough apertures in the bar K. From the bar K the pins K having headsatthcir upper ends, pass through apertures in the bar L, springs Ksurrounding said pins and pressing the bar L downward. The bar K restson the bottoms of the slots in the supports K projecting upward fromarms K, held vertically adjustable on the frame A. On one of thestandards K the Vertically-sliding pin N is pressed downward by thespring N. surrounding it, said pin being provided with an arm, N, whichprojects over a part of the top edge of the bar K. A suitable stop, N,on the said support K pre; vents the spring from pressing the arm N downany farther than a short distance below the lower edge of the upper bar,L. A spring, N is fastened to the frame A, and one end to the bar K, anddraws said bar in the direction ofthe arrow :12, Fig. 5. An arm, N,having its free end notched, is fixed on theupper end of the shaft N",and one of the pins L passes through the said notch. The shaft N has acurved arm, N, on its lower end, one end of which arm N rests againstthe rim of the disk I, mounted on the shaft E. The box G is providedwith downwardly -projecting pins 0, which pass through apertures in theU-shaped plate M, said pins 0 having shoulders or offsets O, which reston the top of said plate M. p

In front of the bars K and L the two dieplates P and Q are provided, theupper dieplate, 1?, being held on the reciprocating crosspiece or hammerG, previously mentioned, and the lower die-holder, Q, being held on avertically-sliding frame, R, mounted to slide between the guides B, saidframe resting on a pin, R, on the front end of a lever, B, piv- IIO otedin the frame and provided with a balanc- The die-plates P and Q areprovided in the edges facing each other with semicircular dies, whichgradually decrease in diameter from the left to the right hand ends ofthe dieplates, as shown in Fig. 1. Pins T project upward from the endsof the box G and are surrounded. by springs T, which serve to press saidbox downward. The die'plates P and Q can easily be removed and replacedby others having notches of different size. Suitable driving-pulleys areprovided on the shaft B.

The operation is as follows: The blanks a, used for making thebnttons,are shown in Fig. 17, and said blanks are inserted between thedie-plates 1? and Q at the left-hand ends of the same, where the dies inthe dieplates are largest. The upper dies reciprocate, and, acting onthe blanks a, draw the sameinward ashort distanceback from the closedend. The blank is then conducted to the next pair of dies to the right,which are slightlysmaller than those in which the blank has just beenlocated, and the metal of the blank (L is drawn in still farther, and soon, until the buttons finally have been in all the dies and leave themachine in the form shown in Fig. 18. From the shaft A the cross-piece Oand the die-plate P on the same are reciproeated, and at the same timethe frame D on the rear end of the machine is reeiprocated, and at eachupstroke of said frame D the ratchet-wheel E on the shaft E is revolvedthe distance of one tooth by the pawl E on the frame D, and thus thecam-wheel S on the front end of the shaft E is revolved accordingly, andas it acts on the projection S of the frame R, in which the bottomdie-plate, Q, is held, said die-plate is gradually raised, and thus thedie-plates P and Q are gradually brought toward each other until thecompletion of the revolution of the cam-disk S, when the frame R dropsand the dieplates P Q are separated. Every time the wheel E, Fig. 2,completes a revolution the disk F on the same also completes arevolution, and the projection F of the said wheel F strikes the arm Fof the shaft F and turns said shaft F in such a manner that the arm F(shown in the vertical position in Fig. 2) is brought into a horizontalposition, and, acting on the lower end of the pawl E*, swings the upperend of said pawl 15* from engagement with the ratchetwheel E and it isthus evident that during the time that the arm F is in horizontalposition the pawl E cannot act on the teeth of said ratchet-wheel Ewhereas during the greater part of the revolution of the wheel E the armF is in vertical position, thus permitting the engaging of the pawl Ewith the ratchet-wheel so that by the vertical reciprocation of theframe D the ratchet-wheel E is revolved. The motion of the ratchet-wheelE is transmitted by the gear-wheels to the tubular shaft F, and from thesame to the shaft G in the box G, Figs. 8 and 9, and from the shaft G tothe several cogwheels G, whereby the rods G are turned on theirlongitudinal axes, as are also the heads Gon the ends of the same. Theflanged ends of the blanks a, located between the dies P and Q, restagainst the rubber disks G of the heads G, and by the actions of thesprings J, surrounding the sleeves G", through which the rods Gr pass,said rubber disks G are pressed firmly against the flanged ends of theblanks a. The rods G are thus revolved, and rotate by frictional contactthe blanks resting against the rubber disks G and thus it is evidentthat the blanks are rotated during the greater part of the revolution ofthe wheel Ethat is, they are revolved as long as the arm F is invertical position and the pawl E is engaged with the ratchet-wheel E Assoon as the projection F of the wheel F acts on the arm F of the shaftF", and the arm F of the shaft F is brought into horizontal position,the pawl E is disengaged from the ratchet-wheel E, and consequently therods Gr come to a standstill and do not rotate the blanks a. Thisrotation of the blanks is necessary, so that they receive each stroke ofthe dies in a different position, as otherwise the metal of the blankswould not be drawn inward, but would be compressed or flattened. Theblanks remain in one pair of dies during one entire revolution of theshaft E, which corresponds to as many blows from the die-plate P asthere are teeth in the wheel E. Every time the wheel E has made arevolution the blanks must be conveyed to the next pair of dies. This isaccomplished in the following manner: As previously stated, the bar K issupported by the standards K. The bar L is supported by means of thepins L" from the plate M, resting on the frame R, and is presseddownward by the springs K". \Vhen the camdisk S is in the position shownin Fig. 1, the frame R is not raised during the first part of therevolution of the said cam-disk, as the part of the cam between theoffset S and the shoulder S is concentric to the center of the disk. Assoon as the arm S has passed the shoulder S the frame R is moved upward,and thus the upper bar, L, which is supported from the plate M on theframe ll, is also moved upward, and so on, until the disk S hascompleted its revolution, when the frame Rsuddcnly drops, andthe bar Ldrops with the frame R and is pressed upon the flanges of the blanks,whereby said blanks are securely held between the bars L and K. If saidbars L and K are now moved to the right the distance from one pair ofdies to the next pair, the blanks will be eont eyed with said bars andwill be shifted from one pair of dies to the next pair. At the same timethat the bar L is moved downward to grasp the blank in the mannerdescribed the end of-the curved arm N snaps off the projection orshoulder l of the cam-disk l on the shaft E, and the spring N draws thebars K and L in the direction of the arrow 00, Fig. 5, whereby the arm N011 the shaft N is moved in the direction of the arrow 00", Fig. 4.

The dieplates P and Q are separated as the arm S of the frame 1%, whichholds the lower die-plate, Q, has dropped off the offset S of the camdisk S the moment before the end of the curved arm N slips off thehighest point or offset, 1 of the cam-disk 1*. After dropping off theoffset 1 of the cam-disk l the end of the arm N runs on the part 1 ofthe rim of the disk I", and as that part I is concentric the IIC arms Nand N on the shaft N are not shifted. During the time that the end ofthe arm N travels on the concentric part I of' the rim of the disk I theframe R is gradually raised, and thereby the bar L is raised and theblanks released, said blanks being now held between the two dies. Thenthe eccentric part ofthe rim of the disk lbegins to act on the end ofthe arm N of the shaft N whereby said arm N and the arm N are moved inthe inverse direction of the arrow as, Fig. 4, and the bars K L moved inthe inverse direction of the arrow as, Fig. 5, ready to shift the blanksagain for the next rotation of the shaft E. The blanks are thus heldloosely between the dies during the operation of drawing inward themetal; but at the end of each revolution of the shaft E the barLdescends upon the rims of the buttons in consequence of the lowering ofthe frame R. Then the bars K L are shifted in the manner set forth, andso on. During the time that the blanks or buttons are being shifted inthe manner set'forth it is necessary that the rubber disks G" on theheads G should be withdrawn. At the same time that the blanks aregrasped or held by the bar L the projection I on the rim of the disk 1acts on the arm I of the shaft z, whereby the arm I of the shaft isswung in the direction of the arrow m, Fig. 4, and acting on the pin Hprojecting downward from the rod H", moves said rod H in the directionof the arrow a, Fig. 9, whereby the arms H are swung in the direction ofthe arrows .10 Fig. 9, and the cam-arms H swung inward, and acting onthe bar H press the same toward the rear of the box, whereby the collarsJ are also pressed to the rear, and as said collars are connected withthe sliding rods G said rods and their heads G are withdrawn from theends of the blanks. After a short time the arm I is disengaged from theprojection I of the disk lfland the springs J expand and press therubber disks G against the blanks, and thus the blanks are revolved, asbefore described.

It is evident that the rods Gr for turning the blanks must ascend anddescend" with the lower die-holder, and for this reason the box G issupported on the plate M, secured on the frame B. From the above it isapparent that for each stroke of the machine a finished button is thrownfrom between the dieplates at the right-hand end of the machine, and afresh button must be introduced at the left-hand edge. The edge of theblank is placed in arecess in the bottom bar, K, and the upper part ofthe blank is pressed down by the arm N Fig. 5. Said blank is then movedin between the die-plates in the manner previously de scribed and.gradually conveyed to the righthand ends of the die-plates.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
